Improved Polishing Machine & Small QOL Update — MineMogul Steam update #204245

Improved Polishing MachinePreviously when the polishing machine got dirty, it just became dirty looking, but it didn't make a sound or play a different animation. It was really easy to completely miss the fact that the Polishing Machine could get dirty. This resulted in a lot of people being confused and thinking it was bugged.Now, when the Polishing Machine becomes dirty, it plays a new animation, the brushes completely stop spinning, and it plays an annoying beeping sound.The Polishing Machine has also been updated to use a generic input instead of a regular conveyor input. Previously it didn't connect to rolling conveyors without using a ledge. Now it does!Audio ImprovementsSome people were having audio issues when creating very large factories with lots of machines.I've done some tweaks that should greatly improve it for this update, but it won't be perfect. I need to improve it some...
